Research on Improving Footprint Simulation Accuracy of All-steel Radial Tire Based on Belt Model
Taking all-steel radial tires with 4 layers of belts structure and 3 layers of belts+0° belt structure as the objects,the influence of the belt model on the simulation accuracy of tire footprint was studied.The results showed that for the tire with 4 layers of belts structure,the belt angle changed after building and curing,and the simulation model could be modified according to the law of belt angle changing,which could improve the simulation accuracy of tire footprint.For the tire with 3 layers of belts+0° belt structure,the hyperelastic model could be used to characterize the high-elongation steel cord with 0° belt layer,which could improve the simulation accuracy of footprint.
